About 12 minutes into the movie Franklyn Drew digs a bullet out of the wall and identifies it as a ".38 caliber center fire." It is impossible to tell from the bullet alone whether it was fired from a center fire or rim fire cartridge. Such a claim could lead to confusion in identifying the gun that fired the bullet.

The onscreen credits misspelled the surname of author Madelon St. Dennis as "St. Denis."

In early scenes while dictating in his office and talking to police, Leon A. Grossmith, the head of the studio, has a "humorous" accent with some inverted word placement. "Murder? Oye!" "A calamity Ve got, ach!" Later, towards the end of the film, he makes "advances" toward Marcia Lane in her dressing room. His accent is gone, he speaks Standard American or General American .

When all the principal characters are gathered in the studio's screening room to watch the footage of Myles Brent being murdered, the lights naturally go out. As it's being projected, the film catches fire. The culprit is seen among those in the screening room when the lights come back on. But there is no time for him to have left the room, knocked out the projectionist, set fire to the film, and returned to the screening room unnoticed.
